Study of the magnetostrictive distortion in single crystal Terfenol-D by X-ray diffraction

X-ray diffraction has been used to study the magnetostrictive distortion in single-crystal Terfenol-D. The magnetostriction coefficient and the linear thermal-expansion coefficient have been determined over the temperature range of +or-100 degrees C from observing the change in shape, diffraction angle, and intensity of the
